I just got the Storm about a week ago and its my first Black Berry. I think I have got most of it but 1 thing gets me that I just cant figure out or you just cant do. I am trying to change text tone to one of my MP3 insted of the defaults. Any help

Go to sounds >> set ringtones / alerts then select what notification you want to change. Next where it lists the sound you click on it and roll to the top where it says browse. Find the tone you want to use and select it!
